- Routine Description:\r
- Get the imageid of last image block: EFI_HII_IIBT_END_BLOCK when input\r
- ImageId is zero, otherwise return the address of the\r
- corresponding image block with identifier specified by ImageId.\r
+ This is a internal function.\r
\r
- Arguments:\r
- ImageBlock - Points to the beginning of a series of image blocks stored in order.\r
- ImageId - If input ImageId is 0, output the image id of the EFI_HII_IIBT_END_BLOCK;\r
- else use this id to find its corresponding image block address.\r
+ @param ImageBlocks Points to the beginning of a series of image blocks stored in order.\r
+ @param ImageId If input ImageId is 0, output the image id of the EFI_HII_IIBT_END_BLOCK;\r
+ else use this id to find its corresponding image block address.\r
\r
- Returns:\r
- The image block address when input ImageId is not zero; otherwise return NULL.\r
+ @return The image block address when input ImageId is not zero; otherwise return NULL.\r
